How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the schema identifier ('delx/util-address-is-zero/v1'), the input address echoed back, and a boolean 'is_zero' field indicating whether the address equals the Ethereum zero address (0x0000000000000000000000000000000000000000).
Example use cases
Pre-transfer address safety check
“Before I send those USDC tokens, can you verify that the recipient address 0xAbCd1234...5678 isn't the zero address so I don't accidentally burn them?”
Smart contract output validation
“The contract just returned this address: 0x0000000000000000000000000000000000000000 — can you confirm whether that's the zero/null address?”
Batch approval guard for DeFi agent
“I'm about to approve a DeFi protocol to spend my tokens. Can you first check that the spender address 0x1234567890abcdef1234567890abcdef12345678 is not the zero address?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/address-is-zero?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, cheap, verifiable on-chain-safe check to determine if an address is the zero address before executing token transfers, approvals, or smart contract interactions. Prefer this over writing custom logic when operating in an agent pipeline that already handles x402 micropayments, since it requires no signup and costs only $0.001 USDC per call.
Side effects
- Missing or malformed address input — may return an error or unexpected result
- Non-checksummed or invalid hex address format may cause validation errors
- Network or payment failure via x402 protocol resulting in no response
